未调用 Android Wear onDataChanged [英] Android Wear onDataChanged isn't called

问题描述

我下载了一个现成的手机应用程序，并尝试为我的 Android Wear 项目实现一个表盘.目标是将温度信息从手机传递到穿戴设备并让它更新表盘.

I downloaded a ready phone app and trying to implement a watchface for my android wear project. The goal is to pass temperature information from phone to the wear device and have it update the watchface.

我试过:1. 相同的包名2.相同的应用程序ID3. 相同的依赖版本4.相同的权限5. 在我的手机端，我确信我的数据每次都不同(因此必须进行更新)

I have tried: 1. same package name 2. same applicationId 3. same dependencies versions 4. same permissions 5. on my phone side I know for sure that my data is different every time (so the update has to happen)

我还使用数据项，因此我的数据必须同步.

I also use data items so my data has to get synced.

private void syncWatch(String min, String max, int image){
    Log.v("SunshineSyncAdapter", "syncWatch");
    String time =  String.valueOf(new Date().getTime());
    PutDataMapRequest putDataMapRequest = PutDataMapRequest.create("/weather-update");
    putDataMapRequest.getDataMap().putLong("time", new Date().getTime()); // MOST IMPORTANT LINE FOR TIMESTAMP

    putDataMapRequest.getDataMap().putString("min-temp", min + time);
    putDataMapRequest.getDataMap().putString("max-temp", max + time);
    Log.v("SunshineSyncAdapter", min + time + " " + max + time);
    PutDataRequest request = putDataMapRequest.asPutDataRequest();

    if (mGoogleApiClient == null){
        Log.v("SunshineSyncAdapter", "NOOOOOOOOOOOOOOOOO, life is no good");
        return;
    }

    Wearable.DataApi.putDataItem(mGoogleApiClient,request).setResultCallback(new ResultCallback<DataApi.DataItemResult>() {


        @Override
        public void onResult(DataApi.DataItemResult dataItemResult) {
            if (!dataItemResult.getStatus().isSuccess()) {
                Log.v("MainActivity", "Something went wrong, watch was not notified");
            } else {
                Log.v("MainActivity", "Success, Watch Notified");
            }
        }
    });
}

我首先在手机上运行我的应用程序，确保它正确运行，并且它已更新并将数据项发送到我的穿戴设备.然后我运行我的磨损模块并没有收到任何信息，因为从未调用过 onDataChanged 方法.

I first run my app on the phone make sure it runs correctly and that it updated and sends data items to my wear device. Then I run my wear module and receive nothing because onDataChanged method is never being invoked.

 @Override
    public void onDataChanged(DataEventBuffer dataEvents) {
        Log.v("SunshineWatchFace", "onDataChanged");
        try{
            for(DataEvent dataEvent: dataEvents){
                if(dataEvent.getType() != DataEvent.TYPE_CHANGED){
                    continue;
                }

                DataItem dataItem = dataEvent.getDataItem();
                if(dataItem.getUri().getPath().compareTo("weather_update") == 0){
                    DataMap dataMap = DataMapItem.fromDataItem(dataItem).getDataMap();
                    minTemp = dataMap.getString("min-temp");
                    maxTemp = dataMap.getString("max-temp");
                    weatherImage = dataMap.getInt("weather-image");
                    Log.v("SunshineWatchFace", minTemp);
                    Log.v("SunshineWatchFace", maxTemp);
                }
            }
            dataEvents.release();
            if(!isInAmbientMode()){
               invalidate();
            }
        }catch (Exception e){
            Log.v("SunshineWatchFace",e.getMessage());
        }
    }

推荐答案

在 GitHub 上向您发送了包含更正的拉取请求.好像你只是忘记连接你的谷歌客户端:)

Sent you a pull request on GitHub with corrections. Seems like you just forget to connect your google client :)

mGoogleApiClient.connect();

还有一些额外的小改动(一些重构).

And some additional small changes in your code (some refactoring).
